Vodacom reporting sent to credit agencies

I notified over a month ago about issues I have with the information that Vodacom is sending to credit scoring agencies. How come Vodacom reports me as a late payer when they have a direct debit in place? Worse still, after having spoken to them on numerous occasions this past month, absolutely nothing has been resolved. The credit agencies confirm that they are receiving reports and cannot check on the validity of these as this is down to Vodacom. Vodacom are sending reports on payments that make absolutely no sense, and the Vodacom customer care do not seem to understand where these come from either .... As it stands I seem to have 2 accounts with Vodacom, but I only opened one 18 years ago ... this is affecting my credit score for absolutely no fault of mine. Please sort it out!!
